Floribunda rose plant named ‘BAIsuhe’

ABSTRACT

A new cultivar of floribunda rose,  Rosa  ‘BAIsuhe’, characterized by its clusters of fragrant, fully double hybrid tea-shaped flowers that are medium red in color suffused with pink highlights as they mature, its dark red flower buds, its everblooming flowering habit, its medium green satiny foliage that is resistant to rose blackspot and powdery mildew, and its rounded and compact plant habit. The new variety is readily propagated on its own roots and hardy in U.S.D.A. Zones 4 to 9.

Botanical classification: Rosa hybrida.

Variety denomination: ‘BAIsuhe’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Rosahybrida. The new cultivar will be referred to hereafter by its cultivarname, ‘BAIsuhe’. ‘BAIsuhe’ is a floribunda rose suitable for landscapeplantings.

The new cultivar of shrub rose is a selection from a controlled breedingprogram conducted by the inventor in Yamhill, Oreg. with a focus tocreate cultivars of roses with greater winter hardiness and improvementsin disease resistance combined with good flower quality.

The new variety of floribunda rose, ‘BAIsuhe’, designated as seedlingNo. 96A723-1R was selected among seedlings derived from a cross made inYamhill, Oreg. in 1996 between the hybrid tea cultivar ‘Silver Jubilee’(not patented) as the female parent and an unnamed proprietary seedlingof the inventor's, No. 93A254, as the male parent. ‘BAIsuhe’ was buddedonto understock in 1996 and selected by the inventor as unique for itsdistinct characteristics in summer of 1999.

The new cultivar has been asexually propagated by budding and rooting ofsoftwood cuttings from a plant grown on its own roots in Yamhill, Oreg.Asexual propagation determined that the characteristics of this cultivarare stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new rose as observed for a period of seven yearsin Yamhill, Oreg., St. Paul, Minn. and several other test sites in theU.S. These attributes in combination distinguish ‘BAIsuhe’ as a uniquecultivar of rose.

-   -   1. ‘BAIsuhe’ exhibits clusters of fully double hybrid tea-shaped        flowers that are medium red in color and suffused with pink as        they mature. The flower buds of ‘BAIsuhe’ are dark red in color.        ‘BAIsuhe’ is classified as a medium red by American Rose Society        standards.    -   2. ‘BAIsuhe’ has fragrant flowers with a medium rose scent.    -   3. ‘BAIsuhe’ exhibits a compact rounded habit with a height of        90 cm to 1.5 m.    -   4. ‘BAIsuhe’ exhibits medium green, satiny foliage.    -   5. ‘BAIsuhe’ exhibits an everblooming habit.    -   6. ‘BAIsuhe’ has shown excellent resistance to rose blackspot        (Diplocarpon rosae) and powdery mildew (Sphaerotheca pannosa        var. rosa).    -   7. ‘BAIsuhe’ is hardy in U.S.D.A. Zones 4 to 9.    -   8. ‘BAIsuhe’ is a vigorous grower and readily propagated by        softwood cuttings and grown on its own roots.        The new cultivar of shrub rose can be readily distinguished from        its parents and other cultivars. The female parent, ‘Silver        Jubilee’, is a hybrid tea rose with very large glossy foliage        and very large fully double flowers that are light golden yellow        in color. The male parent, seedling No. 93A254 has double (not        fully double) red flowers that are smaller in size than those of        ‘BAIsuhe’. The cultivars ‘BAIhero’ (U.S. Plant Pat. No. 15,400)        and ‘John Franklin’ (not patented) are close comparison roses.        They both have similarity to ‘BAIsuhe’ in having double medium        red hybrid tea-shaped flowers. ‘BAIhero’ differs from ‘BAIsuhe’        in having lighter green foliage and larger flowers that have        less petals, are less fragrant, and mature to a pinker color in        comparison to ‘BAIsuhe’. ‘John Franklin’ differs from ‘BAIsuhe’        in having foliage with a matte surface, flowers that have frilly        petals and mature to a deep pink color, pinker flower buds, an        upright rounded plant habit, and a recurrent blooming habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearanceand distinct characteristics of the new floribunda rose, ‘BAIsuhe’, asgrown outdoors in trial blocks and containers in St. Paul, Minn. andYamhill, Oreg. The photographs were taken of four year-old plants grownon their own roots.
